Selling Books Starting With What Not To Do!

Novice writers like me have to wade through a thicket of difficulties.  Setting aside the challenge of what to say and how to say it, when it's done and published, a whole new set of uncertainties kick in.
It may go without saying that I came at the sales question strictly old school.  You know, traveling with a bunch of books in the back seat, contacting indie bookstores, book signings with a handful of customers (or not), local talks, maybe some sort of book tour.
When editor/publisher Greg Pierce suggested connecting with Mary Doyle, I jumped at the chance.  She's been through all this and come out of it with a ton of sales reflective of her learn-by-doing (yeah, trial and error).
I don't think I'm revealing any trade secrets here because whatever the aspiring author/bookseller does depend mostly on the individual - relational assets, energy, and skill sets - that good coaches like Mary and Greg build on. The first key point that came through loud and clear: What not to do.  Uh, oh!  The what-not-to-do's line up pretty well with what I thought I had to do - the old school stuff.  (To be continued as the plot thickens.)
